TMP/R α Q (under steady temperature)
In these general models, we are divided into resistance:
R＝R m+R pot
And Q iα TMP/ (R m+ R Pot)
Wherein, Q iBe the flow that occurs from complete fiber top, R mBe the module resistance, R PotIt is resistance across jar.
We suppose R mBe constant-a kind of mean value-but it will be along the length of fiber and changes.
The supposition fiber is in tank deck fracture (filtrate is through the worst case of bypass) now.At this moment:
R m＝0
And Q bα TMP/R Pot
Wherein, Q bIt is the flow of filtrate that occurs from the broken fibre top.
Be calculated as follows along the flow of broken fibre and ratio along the flow of complete fiber:
Q b/Q i＝(R m+R pot)/R pot
＝1+R m/R pot
Under normal circumstances, R m＞＞R Pot-common 20.Therefore can know that the fiber of fracture allows a large amount of supplies, thereby pollute filtrate, and therefore reduce strainability.In addition, increase fibre inner diameter usually because R Potα L/d 4And the problem that makes becomes more serious, and wherein, d is a lumen diameter, and L is the length of jar.
Therefore, wish the flow of filtrate of reduction from broken fiber.Suppose that we increase R Pot(for example by increasing L or reducing d).Q b/ Q iLimiting value trend 1.This is the result who wishes most.But the length that increases jar others improper-it has increased the length of module and the expense of module and processing.Other selection is the internal diameter that reduces the fiber in the jar.
